Quote: 12Z GFS, west even more, stalls out along the coast south of Morgan City, LA Wednesday morning. Puts New Orleans with the dirty side of the storm, and then SLOWLY moves westward in or along the coast of Louisiana.
The tide wouldn't go out it would just get higher. This is based on the Rigolets and Lakes Bourne and Ponchartrain tides. Water gets blown into these areas and can't get out. ( Well it can get out but it ain't pretty, floods New Orleans if it goes out that way)
